GEORGE DOUGLASS, OF SIOUX CITY, IO\VA.

SPECIFICATION Application filed April 18, 188-1.

T0 (ZZZ whom it may concern.-

Be it known that I, GEORGE DOUGLASS, a citizen of the United States, residing at Sioux City, in the county of lVoodbury and State of Iowa, have invented certain new and useful Improvements in Vapor-Generators for Baths and Bath Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to portable vaporbaths; and the novelty consists in the con-' struction, arrangement, and adaptation of a peculiar vaporgenerator in its relation to the batlrcloset, as will be more fully herein after set forth, and specifically pointed out in the claim.

Theinvention is illustrated in the accompanying drawings, which form a part of this specification, and in which Figure 1 is an elevation showing the relative arrangement of the generator and closet; Fig. 2, a horizontal section of the generator; Fig. 3, a vertical section otthe same; Fig. 4, an end view of the fire-box, showing it surrounded by water.

I will briefly describe the bath-closet, although it forms only a relative feature of the invention.

A designates the body ofthe closet, having a seat, a foot-rest, E, a side door, (J, a hinged top, B, and a sectional top, B, adapted to closely embrace the neck of the person being treated. A lamp, R, may be employed to produce chemical or medicinal fumes or vapor, and an attachment may be provided, if desired.

I desire to inject into the interior of this closet, when cl osed,a proper quantity of steam. To this end I provide the generator F. This is essentially a. sheet-metal vessel having a fire-chamber, H, a deflectirig-chamber, I, a water chamber connected with the exterior by a passage, f, and an escape-flue, as L. The water-chamber entirely surrounds the heat-fines, except the front of the lire-box, and the said fire-box is connected to the deflecting-chamber by a series of pipes, as K.

Suspended in the chamber I is a deflector, I, which is held in position by small cleats part of Letters Patent No. 327,539, dated October 6, 1885.

Serial No. 128,407. (No model.)

or brackets t. The lower surface of the deflector is inclined outwardly, and the exit from the chamber for the products of combustion is located at the top and, approximately, the center of the deflector, as seen at IJ.

The rising products of combustion meet the deflector in their passage to the exit, and are thrown toward the sides and along the top of the chamber. The reverberations of the heat products thus caused by the deflector allows the maximum of heat to be given off to the surrounding water. A pipe, G, connects the interior of this generator above the waterlevel with the interior of the closet A through a pipe, M, or other proper coupling means.

I deem it important that the water-chamber G so nearly surrounds the several fireflues in order to quickly generate steam, and that the deflector checks the draft to allow the surrounding water to collect a maximum quantity of the heat.

I am aware that fire-flues arranged in a water-chamber have been used for other purposes, and that deflectors have been employed to change the direction and check a draft, and therefore claim only the devices of the specific construction and combination as hereinafter pointed out.

\Vhat I claim as new is- The portable steam-generator consisting of a vessel with a horizontal firebox located in the interior thereof and entirely surrounded by water, except at the exterior opening, a series of ilues passing therefrom, a chamber to which the lines pass in the upper portion of said vessel and over the fire-box, a deflector suspended in said chamber, an escapepipe leading therefrom, and a steam-eonuecting pipe projecting from the top of said vessel, the whole combined and adapted to serve in connection with a bath-closet, substantially as and for the purpose specified.

In testimony whereof I have affixed my signature in presence of two witnesses.

GEO. DOUGLASS.
